[0033] The network device in the embodiment of the present application may be a device for communicating with a terminal device, and the network device may also be referred to as an access network device or a wireless access network device, such as a base station. The network device in the embodiment of the present application may refer to a wireless access network (RAN) node (or device) that connects a terminal device to a wireless network. Base station can broadly cover various names as follows, or replace with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station MeNB, auxiliary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, base band unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof.

[0034] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0035] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device includes a CU and a DU. The gNB may also include an AAU.

[0036] The network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons and satellites in the air. The embodiments of the present application do not limit the scenarios in which the network equipment and terminal equipment are located.

[0037] It should be understood that all or part of the functions of the communication device in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (eg, a cloud platform).

[0038] The introduction of 5G networks has greatly increased the data rate that the network can transmit, and can support high-speed transmission of the first service. Since the rate of the first service is high, it needs to be quickly adjusted to adapt to the network environment.

[0039] In some implementations, the first service may be an extended reality (XR) service, for example, an augmented reality (AR), virtual reality (VR), mixed reality (MR), or the like.

[0040] Taking the first service as XR service as an example, the characteristics of XR service are large data volume, high data transmission rate requirements, and very demanding data transmission delay requirements. All indicators are much higher than existing services. Therefore, even 5G networks can hardly support a large number of terminal devices to transmit XR services at the same time. On the other hand, most of the XR service data belongs to video data. The service rate of video data depends on video encoding. If the video encoding is more detailed and high-definition, the data volume will be large; conversely, if the video encoding slightly reduces the clarity, the data volume will be reduced. The temporary reduction in data volume is not immediately noticeable to users because of the temporary reduction in data rate. This characteristic of video encoding provides space for rate adjustment of XR services. When the network is congested, the XR service rate of the terminal device can be temporarily adjusted, and the XR service rate can be restored after the congestion ends.

[0041] In the communication system, the rate adjustment of the first service is achieved through negotiation between application layers, but this rate adjustment method is slow and may affect data transmission of the first service.

[0042] The following takes the first service as an example, combining Figure 2 This section describes the process of determining and adjusting the first service rate.

[0043] exist Figure 2 In the process, if the XR application (APP) layer of the terminal device needs to establish an XR service, it initiates an XR service request through a non-access stratum (NAS) message, which includes the uplink rate and downlink rate requested by the XR application layer on the terminal device side. Upon receiving the request, the core network element obtains the quality of service (QoS) parameters of the XR service from the XR server (server), including uplink rate, downlink rate, delay budget, etc., and notifies the access network device (for example, gNB). The access network device determines the wireless interface parameters corresponding to the XR service based on the QoS parameters, and configures the wireless parameters suitable for the XR service for the terminal device through a radio resource control (RRC) reconfiguration message. At the same time, the core network element sends a NAS message to the terminal device, that is, Figure 2 In the "XR Service Response" in the service establishment process, configure NAS parameters for the terminal device. After the process is completed, XR data begins to be transmitted, and its data transmission rate is processed according to the uplink rate and downlink rate described in the service establishment process. It is worth noting that Figure 2 The core network elements in the network actually include multiple specific network elements. For example, for 5G, it can be the access and mobility management function (AMF) and the session management function (SMF). These two nodes have different divisions of labor. The AMF directly interacts with the access network equipment and terminal equipment, but the specific parameters of the XR service are determined by the SMF. Figure 2 AMF and SMF are represented by core network elements.

[0044] If the wireless interface changes during the transmission process, and the rate of the supported XR service changes accordingly, the access network device and the terminal device will interact through the medium access control element (MAC CE) to adjust the service rate, and then the medium access control (MAC) entity of the terminal device will notify the application layer of the terminal device. Specifically, the access network device notifies the terminal device of the expected uplink rate and downlink rate through the MAC CE "Recommended bit rate MAC CE". After the MAC entity of the terminal device learns of the expected rate of the wireless interface, it negotiates with the XR server through the application layer process. After the two parties reach an agreement, the application layer of the terminal device and the XR server adjust their own encoding parameters according to the expected rate of the wireless interface, so that the encoder outputs the data stream at the expected output rate. Figure 2 In the example shown, taking the reduction of XR data rate as an example, a thick line indicates a high data transmission rate, and a thin line indicates a reduced data transmission rate.

[0045] There are two problems with the above process: one problem is that the uplink and downlink rates of the XR service are negotiated between the application layers, and the response to adjusting the rate is slow; the other problem is that the uplink and downlink rates of the XR service are negotiated between the application layers, which requires additional air interface message transmission. If there are many users and the network is congested, these additional control message transmissions will need to wait for a long time, or the wireless interface will deteriorate and the messages will need to take longer to transmit. Both of these situations will cause the negotiation process to last longer.

[0046] In view of the above problems, an embodiment of the present application provides a method for wireless communication, in which a network device sends first information to a terminal device and / or a first network element, and the first information is used to determine an uplink rate and / or a downlink rate of a first service, and there is a correlation between the uplink rate and the downlink rate. The network device sends the first information to the terminal device and / or the first network element to adjust the rate of the first service, which can omit the negotiation of the application layer and does not require additional air interface message transmission, which helps to speed up the process of adjusting the rate of the first service.

[0047] Combined with the following Figure 3 A wireless communication method according to an embodiment of the present application is introduced. Figure 3 It is a schematic flowchart of the wireless communication method of an embodiment of the present application. Figure 3 The method shown includes step S310.

[0048] In step S310, the network device sends first information to the terminal device. Correspondingly, the terminal device receives the first information sent by the network device.

[0049] In some implementations, the network device may also send the first information to the first network element. Correspondingly, the first network element receives the first information sent by the network device.

[0050] In some implementations, the first information sent by the network device to the first network element is forwarded to the first network element through other network elements.

[0051] In some implementations, the other network elements may be core network elements, and the core network elements include AMF and / or SMF. For example, the network device is an access network device, the access network device notifies the AMF of the first information, and the AMF forwards the first information to the first network element. For another example, the access network device notifies the AMF of the first information, the AMF forwards the first information to the SMF, and after the SMF obtains the first information, it forwards the first information to the first network element.

[0052] It should be noted that the first network element may be a server of the first service. For example, the first network element is the XR server mentioned above.

[0053] In some implementations, the first information is used to determine an uplink rate and / or a downlink rate of the first service. That is, based on the first information, the uplink rate and / or the downlink rate of the first service can be determined.

[0054] In some implementations, the uplink rate of the first service may be understood as the updated transmission rate of uplink data of the first service, or the adjusted transmission rate of uplink data of the first service.

[0055] In some implementations, the downlink rate of the first service may be understood as the updated transmission rate of downlink data of the first service, or the adjusted transmission rate of downlink data of the first service.

[0056] In some implementations, there is an association relationship between the uplink rate of the first service and the downlink rate of the first service, or in other words, there is a correlation between the uplink rate of the first service and the downlink rate of the first service.

[0057] In some implementations, the first association information may be used to indicate an association relationship between an uplink rate of the first service and a downlink rate of the first service.

[0058] In some implementations, the first association information includes one or more of the following: a first index; an uplink rate; a downlink rate; a range of uplink rates; a range of downlink rates; and a first parameter.

[0059] In some implementations, the first index is used to indicate a combination of an uplink rate and a downlink rate, or a combination of an uplink rate range and a downlink rate range. For example, referring to Table 1, the first index is 0, indicating that when the uplink rate is A, the associated downlink rate is A'. For another example, referring to Table 2, the first index is 1, indicating that the uplink rate range is [C, D], and the associated downlink rate range is [C', D'].

[0060] Table 1

[0061] Index value Uplink rate Downlink rate 0 A A′ 1 B B′ 2 C C′

[0062] Table 2

[0063] Index value Uplink rate range Downlink rate range 0 [A,B] [A′,B′] 1 [C,D] [C′,D′] 2 [E,F] [E′,F′]

[0064] In some implementations, the first parameter is used for one or more of: determining a downlink rate based on an uplink rate; determining a range of downlink rates based on a range of uplink rates; determining an uplink rate based on a downlink rate; determining a range of uplink rates based on a range of downlink rates.

[0065] In some implementations, if the first parameter is used to determine the downlink rate based on the uplink rate, or to determine the uplink rate based on the downlink rate, the first parameter can be used to indicate one or more of the following: an offset value between the uplink rate and the downlink rate; a ratio between the uplink rate and the downlink rate; a ratio between the downlink rate and the uplink rate.

[0066] In some implementations, if the first parameter is used to determine the range of the downlink rate based on the range of the uplink rate, or to determine the range of the downlink rate based on the range of the uplink rate, the first parameter can be used to indicate one or more of the following: an offset value between the upper boundary of the uplink rate range and the upper boundary of the downlink rate range; an offset value between the lower boundary of the uplink rate range and the lower boundary of the downlink rate range; a ratio between the upper boundary of the downlink rate range and the upper boundary of the uplink rate range; a ratio between the lower boundary of the downlink rate range and the lower boundary of the uplink rate range; a ratio between the upper boundary of the uplink rate range and the upper boundary of the downlink rate range; a ratio between the lower boundary of the uplink rate range and the lower boundary of the downlink rate range.

[0067] In some implementations, the first association information includes a first index. Accordingly, based on the first index, the uplink rate and the downlink rate can be determined. For example, the first association information includes the first index, the first index is the index value 2 in Table 1, and based on the first index, the uplink rate can be determined to be C and the downlink rate can be determined to be C′.

[0068] In some implementations, the first associated information includes an uplink rate and a downlink rate. For example, referring to Table 1, the first associated information includes uplink rates A, B, and C and downlink rates A', B', and C' associated with the uplink rates.

[0069] In some implementations, the first associated information includes an uplink rate and a downlink rate which may be the same or different. For example, referring to Table 1, the first associated information includes an uplink rate A and a downlink rate A', and A and A' may be the same or different.

[0070] In some implementations, if the uplink rate is the same as the downlink rate, the first association information may include only the uplink rate, or only the downlink rate.

[0071] In some implementations, the first association information includes an uplink rate range and a downlink rate range. For example, referring to Table 2, the first association information includes an uplink rate range [A, B], [C, D], and [E, F] and a downlink rate range associated with the uplink rate range [A, B], [C, D], and [E, F]. ′ ,B ′ ]、[C ′ ,D′] and [E′,F′].

[0072] In some implementations, the first association information includes an uplink rate range and a downlink rate range that may be the same or different. Referring to Table 2, the first association information includes an uplink rate range [A, B] and a downlink rate range associated with the uplink rate range [A′, B′], and [A, B] and [A′, B′] may be the same or different.

[0073] In some implementations, if the range of the uplink rate is the same as the range of the downlink rate, the first association information may include only the range of the uplink rate, or only the range of the downlink rate.

[0074] In some implementations, the first associated information includes an uplink rate and a first parameter, the first parameter includes a first offset value, and the first offset value is used to indicate an offset value between the uplink rate and the downlink rate. Accordingly, based on the first offset value and the uplink rate, the downlink rate can be determined. For example, referring to Table 3, the first associated information includes uplink rates A, B, and C, and a first offset value, and the first offset value includes A_offset, B_offset, and C_offset. Accordingly, based on the first offset value and the uplink rates A, B, and C, the downlink rates associated with the uplink rates A, B, and C can be determined to be A+A_offset, B+B_offset, and C+C_offset.

[0075] Table 3

[0076] Index value Uplink rate Downlink rate 0 A A+A_offset 1 B B+B_offset 2 C C+C_offset

[0077] In some implementations, the first associated information includes a downlink rate and a first parameter, the first parameter includes a first offset value, and the first offset value is used to indicate an offset value between an uplink rate and a downlink rate. Accordingly, based on the first offset value and the downlink rate, the uplink rate can be determined. For example, the first associated information includes downlink rates A', B', and C', and the first offset value includes A'_offset, B'_offset, and C'_offset. Accordingly, based on the first offset value and the downlink rates A', B', and C', the uplink rates associated with the downlink rates A', B', and C' can be determined to be A'+A'_offset, B'+B'_offset, and C'+C'_offset.

[0078] In some implementations, the first offset value may be a positive value or a negative value. For example, referring to Table 3, the first offset value includes A_offset, which may be a positive value or a negative value. If A_offset is a positive value, the downlink rate is greater than the uplink rate; if A_offset is a negative value, the downlink rate is less than the uplink rate. It should be noted that in order to ensure that the downlink rate is greater than 0, when A_offset is a negative value, the absolute value of A_offset should be less than A.

[0079] In some implementations, the first associated information includes an uplink rate range and a first parameter, the first parameter includes a second offset value and a third offset value, the second offset value is used to indicate an offset value between a lower boundary of the uplink rate range and a lower boundary of the downlink rate range, and the third offset value is used to indicate an offset value between an upper boundary of the uplink rate range and an upper boundary of the downlink rate range. Accordingly, based on the second offset value, the third offset value and the uplink rate range, the downlink rate range can be determined. For example, referring to Table 4, the first associated information includes an uplink rate range [A, B], [C, D] and [E, F], and a second offset value and a third offset value, the second offset value includes A_offset, C_offset and E_offset, and the third offset value includes B_offset, D_offset and F_offset. Accordingly, based on the second offset value, the third offset value and the uplink rate range [A, B], [C, D] and [E, F], it can be determined that the downlink rate range associated with the uplink rate range [A, B], [C, D] and [E, F] is [A+A_offset, B+B_offset], [C+C_offset, D+D_offset] and [E+E_offset, F+F_offset].

[0082] In some implementations, the first associated information includes a range of downlink rates and a first parameter, the first parameter includes a second offset value and a third offset value, the second offset value is used to indicate an offset value between a lower boundary of an uplink rate range and a lower boundary of a downlink rate range, and the third offset value is used to indicate an offset value between an upper boundary of an uplink rate range and a lower boundary of an uplink rate range. Accordingly, based on the second offset value, the third offset value and the range of the downlink rate, the range of the uplink rate can be determined. For example, the first associated information includes a downlink rate range of [A′, B′], [C′, D′] and [E′, F′], and a second offset value and a third offset value, the second offset value includes A′_offset, C′_offset and E′_offset, and the third offset value includes B′_offset, D′_offset and F′_B. Accordingly, based on the second offset value, the third offset value and the range of downlink rates [A′, B′], [C′, D′] and [E′, F′], it can be determined that the range of uplink rates associated with the range of downlink rates [A′, B′], [C′, D′] and [E′, F′] are [A′+A′_offset, B′+B′_offset], [C′+C′_offset, D′+D′_offset] and [E′+E′_offset, F′+F′_offset].

[0083] In some implementations, the second offset value and / or the third offset value may be a positive value or a negative value.

[0084] In some implementations, the second offset value and the third offset value may be the same or different. For example, referring to Table 4, when the index value is 0, the second offset value includes A_offset, and the third offset value includes B_offset, and A_offset and B_offset may be the same or different.

[0085] In some implementations, if the second offset value and the third offset value are the same, the first association information may include at least one of the second offset value and the third offset value. For example, referring to Table 4, when the index value is 0, the second offset value includes A_offset, the third offset value includes B_offset, and if A_offset is the same as B_offset, the first association information may include at least one of A_offset and B_offset.

[0086] In some implementations, the first associated information includes an uplink rate and a first parameter, the first parameter includes a first ratio, and the first ratio is used to indicate the ratio between the downlink rate and the uplink rate. For example, referring to Table 5, the first associated information includes uplink rates A, B, and C, and the first ratio, and the first ratio includes k_a, k_b, and k_c. Accordingly, based on the first ratio and the uplink rates A, B, and C, it can be determined that the downlink rates associated with the uplink rates A, B, and C are A*k_a, B*k_b, and C*k_c.

[0087] Table 5

[0088] Index value Uplink rate Downlink rate 0 A A*k_a 1 B B*k_b 2 C C*k_c

[0089] In some implementations, the first associated information includes a downlink rate and a first parameter, the first parameter includes a second ratio, and the second ratio is used to indicate the ratio between the uplink rate and the downlink rate. Accordingly, based on the second ratio and the downlink rate, the uplink rate can be determined. For example, the first associated information includes downlink rates A', B' and C' and a second ratio, and the second ratio includes k_a', k_b' and k_c'. Accordingly, based on the second ratio and the downlink rates A', B' and C', the uplink rates associated with the downlink rates A', B' and C' can be determined to be A'*k_a', B'*k_b' and C'*k_c'.

[0090] In some implementations, the first associated information includes a range of uplink rates and a first parameter, the first parameter includes a third ratio and a fourth ratio, the third ratio is used to indicate the ratio between the lower boundary of the range of downlink rates and the lower boundary of the range of uplink rates, and the fourth ratio is used to indicate the ratio between the upper boundary of the range of downlink rates and the upper boundary of the range of uplink rates. Accordingly, based on the range of uplink rates, the third ratio and the fourth ratio, the range of downlink rates can be determined. For example, referring to Table 6, the first associated information includes the uplink rate ranges [A, B], [C, D] and [E, F], the third ratio and the fourth ratio, the third ratio includes k_a, k_c and k_e, and the fourth ratio includes k_b, k_d and k_f. Accordingly, based on the third ratio, the fourth ratio and the uplink rate range [A, B], [C, D] and [E, F], it can be determined that the downlink rate range associated with the uplink rate range [A, B], [C, D] and [E, F] is [A*k_a, B*k_b], [C*k_c, D*k_d] and [E*k_e, F*k_f].

[0091] Table 6

[0092] Index value Uplink rate range Downlink rate range 0 [A,B] [A*k_a,B*k_b] 1 [C,D] [C*k_c,D*k_d] 2 [E,F] [E*k_e,F*k_f]

[0093] In some implementations, the first associated information includes a range of downlink rates and a first parameter, the first parameter includes a fifth ratio and a sixth ratio, the fifth ratio is used to indicate the ratio between the lower boundary of the range of the uplink rate and the lower boundary of the range of the downlink rate, and the sixth ratio is used to indicate the ratio between the upper boundary of the range of the uplink rate and the upper boundary of the range of the downlink rate. Accordingly, based on the range of the downlink rate, the fifth ratio and the sixth ratio, the range of the uplink rate can be determined. For example, the first associated information includes the range of downlink rates [A′, B′], [C′, D′] and [E′, F′], the fifth ratio and the sixth ratio, the fifth ratio includes k_a′, k_c′ and k_e′, and the sixth ratio includes k_b′, k_d′ and k_f′. Accordingly, based on the fifth ratio, the sixth ratio and the range of downlink rates [A′, B′], [C′, D′] and [E′, F′], it can be determined that the range of uplink rates associated with the range of downlink rates [A′, B′], [C′, D′] and [E′, F′] are [A′*k_a′, B′*k_b′], [C′*k_c′, D′*k_d′] and [E′*k_e′, F′*k_f′].

[0094] In some implementations, the third ratio, the fourth ratio, the fifth ratio, and the sixth ratio may be integers or decimals.

[0095] In some implementations, the third ratio and the fourth ratio may be the same or different. For example, the third ratio includes k_a, and the fourth ratio includes k_b, and k_a and k_b may be the same or different.

[0096] Similarly, the fifth ratio and the sixth ratio may be the same or different.

[0097] In some implementations, if the third ratio is the same as the fourth ratio, the first association information may include at least one of the third ratio and the fourth ratio. For example, the third ratio includes k_a, the fourth ratio includes k_b, and if k_a is the same as k_b, the first association information may include at least one of k_a and k_b.

[0098] Similarly, if the fifth ratio is the same as the sixth ratio, the first association information may include at least one of the fifth ratio and the sixth ratio.

[0099] In some implementations, the first association information described above may be defined by a protocol. For example, the protocol defines the uplink rate and downlink rate of the first service in Tables 1 to 6, or the range of the uplink rate and the range of the downlink rate of the first service.

[0100] In some implementations, the first association information is known to the terminal device and / or the first network element.

[0101] In some implementations, the terminal device already knows the first association information, which can be understood as the application layer of the terminal device already knows the first association information.

[0102] In some implementations, the uplink rate and / or downlink rate of the first service is associated with the wireless conditions, that is, the uplink rate and / or downlink rate of the first service can be determined based on the wireless conditions, or the uplink rate and / or downlink rate of the first service that can be supported by the wireless interface can be determined according to the wireless conditions.

[0103] In some implementations, the radio condition may be indicated using a result of a radio resource management (RRM) measurement. For example, the radio condition may be indicated using one or more of the following: a channel quality indicator (CQI); a signal-to-noise ratio (SNR); and a signal-to-noise plus interference power ratio (SINR). For example, the SNR indicates the radio condition, and the uplink rate of the first service is determined based on the SNR.

[0104] In some implementations, the first information includes one or more of the following: a downlink rate of the first service; an uplink rate of the first service; a first uplink rate; a first downlink rate; a first uplink rate range; and a first downlink rate range.

[0105] In some implementations, the first uplink rate is an uplink rate of the first service expected by the network device, and the first uplink rate is also referred to as a “target uplink rate”.

[0106] In some implementations, the uplink rate of the first service expected by the network device may be understood as the uplink rate of the first service determined by the network device.

[0107] In some implementations, the first uplink rate is a downlink rate of the first service expected by the network device, and the first downlink rate is also referred to as a “target downlink rate”.

[0108] In some implementations, the uplink rate of the first service expected by the network device may be understood as the downlink rate of the first service determined by the network device.

[0109] In some implementations, the first uplink rate range is a range of uplink rates of the first service expected by the network device, and the first uplink rate range is also referred to as a “target uplink rate range”.

[0110] In some implementations, the range of the uplink rate of the first service expected by the network device may be understood as the range of the uplink rate of the first service determined by the network device.

[0111] In some implementations, the first uplink rate range is a range of downlink rates of the first service expected by the network device, and the first downlink rate range is also referred to as a “target downlink rate range”.

[0112] In some implementations, the range of the downlink rate of the first service expected by the network device may be understood as the range of the downlink rate of the first service determined by the network device.

[0113] In some implementations, the timing at which the network device sends the first information to the terminal device and / or the first network element may be determined based on the wireless conditions and / or the network congestion situation, that is, the rate adjustment process of the first service initiated by the network device is triggered based on the wireless conditions and / or the network congestion situation. For example, the first service is an XR service. During the transmission of the XR service, if the wireless conditions change, such as the wireless conditions deteriorate, the network device may send the first information to the terminal device and / or the first network element to reduce the rate of the XR service of the terminal device and free up wireless resources to transmit service data for other terminal devices. At this time, it is necessary to reduce the rate of the XR service of the terminal device, and wait until the wireless conditions of the terminal device improve, and then send the first information to increase the rate of its XR service. For another example, if the network is congested, even if the wireless conditions of the terminal device do not change significantly, the network device may send the first information to the terminal device and / or the first network element to reduce the rate of the XR service of the terminal device, and wait until the congestion is relieved, and then send the first information to increase the rate of its XR service.

[0114] In some implementations, the first information sent by the network device to the terminal device can be carried in an RRC message or a MAC CE.

[0115] In some implementations, the RRC message carrying the first information may be an RRC reconfiguration message.

[0116] In some implementations, the MAC CE carrying the first information may be a MAC CE in an existing protocol or a newly defined MAC CE. For example, the first information is carried in an existing "Recommended bit rate MAC CE".

[0117] In some implementations, if the first information includes a first uplink rate range and / or a first downlink rate range, which is not supported by a MAC CE in an existing protocol, the MAC CE carrying the first information may be a newly defined MAC CE.

[0118] In some implementations, the newly defined MAC CE may be identified using a logical channel identity (LCID) or an extended logical channel identity (eLCID).

[0119] In some implementations, after receiving the first information, the terminal device notifies the application layer of the first service.

[0120] In some implementations, if the network device sends the first information via an RRC message, the RRC layer of the terminal device notifies the application layer of the terminal device after receiving the first information. Figure 4 , the network device sends the first information to the terminal device through an RRC message, and after the RRC layer of the terminal device receives the first information, it notifies the application layer of the terminal device.

[0121] In some implementations, if the network device sends the first information via a MAC CE message, the MAC layer of the terminal device notifies the application layer of the terminal device after receiving the first information. For example, the network device is a gNB, the gNB sends the first information to the terminal device via a MAC CE, the MAC layer of the terminal device receives the first information, and notifies the application layer of the terminal device.

[0122] In some implementations, the network device is an access network device, and the access network device sends the first information to the first network element via a next generation (NG) interface message, that is, the first information sent by the network device to the first network element is carried in the NG interface message.

[0123] In some implementations, the access network device sends the first information to the first network element via an NG interface message. It can be understood that the access network device notifies the first network element of the first information via the core network element via the NG interface message.

[0124] In some implementations, the core network element may include SMF and / or AMF. Figure 4 The first service is the XR service, the access network device is the gNB, the core network elements are the SMF and the AMF, the first network element is the XR server, and the gNB notifies the AMF of the first information through the NG interface message, and then forwards it through the SMF to notify the XR server of the first information.

[0125] As can be seen from the above, there is a correlation between the uplink rate and the downlink rate of the first service, and this characteristic must be met when adjusting the uplink rate and the downlink rate of the first service. In the traditional solution, when the application layer negotiates the rate adjustment, both application layers know the above correlation, so there will be no problem. However, if the uplink rate and the downlink rate of the first service are adjusted by the network device sending the first information, the network device does not know the correlation between the uplink rate and the downlink rate of the first service, and the determined expected rate may not meet the application layer requirements, resulting in a reduced experience of the first service.

[0126] To solve this problem, in order to make the uplink rate and / or downlink rate of the first service determined based on the first information correlated, before the network device sends the first information to the terminal device and / or the first network element, the network device can obtain the first associated information. The following introduces a solution for the network device to obtain the first associated information from the terminal device or the first network element through Example 1.

[0127] Embodiment 1: A network device obtains first association information.

[0128] In some implementations, the network device obtains the first association information from the terminal device or the first network element. Accordingly, before receiving the first information, the terminal device or the first network element sends the first association information to the network device.

[0129] In some implementations, the network device obtains the first association information from the OAM.

[0130] In some implementations, the network device may obtain the first association information from the terminal device through an RRC message or through a MAC CE.

[0131] In some implementations, if the network device obtains the first association information from the terminal device via an RRC message, the RRC message may be UE Assistance information.

[0132] In some implementations, the terminal device sends the first association information to the network device via an RRC message. It can be understood that the application layer of the terminal device notifies the RRC layer of the terminal device of the first association information via an inter-layer primitive, and the RRC layer of the terminal device then sends the first association information to the network device via an RRC message.

[0133] In some implementations, if the network device obtains the first association information from the terminal device via a MAC CE, the MAC CE may be a MAC CE in an existing protocol, or a newly defined MAC CE.

[0134] In some implementations, the network device obtains the first association information from the first network element by obtaining the first association information from the first network element through a core network element. For example, the first network element is an XR server, the network device is an access network device, the core network element includes an SMF and an AMF, the XR server notifies the SMF, the SMF notifies the AMF, and the AMF notifies the access network device.

[0135] In some implementations, after the network device obtains the first associated information, it determines the uplink rate and downlink rate of the first service according to the first associated information and the wireless condition. For example, the network device is a base station, and the first associated information received by the base station is the three groups of uplink rates and downlink rates in Table 1. The base station determines the uplink rate and downlink rate of the first service to be A and B respectively according to the scheduling algorithm, combined with Table 1 and the wireless condition.

[0136] In some implementations, the network device sends first information to the terminal device and the first network element, where the first information includes an uplink rate and a downlink rate of the first service.

[0137] In some implementations, the first information sent by the network device to the terminal device may include the uplink rate and the downlink rate of the first service, or only include the uplink rate of the first service.

[0138] In some implementations, the first information sent by the network device to the first network element may include an uplink rate and a downlink rate of the first service, or only include the downlink rate of the first service.

[0139] In some implementations, after receiving the first information, the terminal device and the first network element adjust the data transmission rate of their respective first services. For example, if the first service is an XR service, after receiving the first information, the terminal device adjusts the rate at which it sends XR service data to the uplink rate of the XR service included in the first information; and after receiving the first information, the first network element adjusts the rate at which it sends XR service data to the downlink rate of the XR service included in the first information.

[0140] For ease of understanding, the following Figure 4 The solution of Example 1 is introduced by way of example. Figure 4 The steps include step S410 to step S440.

[0141] Assume that the first service is an XR service, the network device is an access network device, the access network device sends the first information to the first network element through the core network network element, the first network element is an XR server, the access network device is a gNB, and the core network network elements include SMF and AMF.

[0142] In step S410, the terminal device sends first association information to the gNB.

[0143] The application layer of the terminal device notifies the RRC layer of the terminal device of the first association information through an inter-layer primitive, and the RRC layer of the terminal device sends the first association information to the gNB through an RRC message.

[0144] In step S420, the gNB determines the uplink rate and downlink rate of the XR service.

[0145] The gNB determines the uplink rate and downlink rate of the XR service based on the first association information and wireless conditions.

[0146] In step S430, the gNB sends first information to the XR server.

[0147] The gNB notifies the AMF of the first information through the NG interface message, and then forwards it through the SMF to notify the XR server of the first information, where the first information includes the downlink rate of the XR service.

[0148] In step S440, the gNB sends first information to the terminal device.

[0149] The gNB sends the first information to the terminal device through an RRC message. The RRC layer of the terminal device receives the first information and notifies the application layer of the terminal device. The first information includes the uplink rate of the XR service.

[0150] In the method in the above-mentioned embodiment 1, the network device needs to obtain the first associated information, and an additional process needs to be introduced. In some implementations, the network device does not need to obtain the first associated information, and only needs the terminal device and / or the first network element to know the first associated information. When the network device believes that the rate of the first service needs to be adjusted, the network device sends the first information to the terminal device and / or the first network element, and the first information includes one or more of the following: the first uplink rate and / or the first downlink rate; the first uplink rate range and / or the first downlink rate range; the uplink rate of the first service or the downlink rate of the first service. Since the first information may include the rate of the first service expected by part or all of the network device, or include the unilateral rate of the first service determined by the network device (such as the uplink rate or downlink rate of the first service), after receiving the first information, the terminal device and / or the first network element that knows the first associated information can determine the final adjusted rate of the first service based on the first associated information.

[0151] The following describes a solution in which the network device does not obtain the first association information through Example 2.

[0152] Embodiment 2: The network device does not obtain the first association information.

[0153] In some implementations, the network device does not obtain the first association information, but the network device knows that the terminal device and / or the first network element already knows the first association information.

[0154] In some implementations, the network device is aware of the first association information known to the terminal device and / or the first network element based on a predefined or operation administration and maintenance (OAM) configuration.

[0155] Implementation method 2-1: The first information includes a first uplink rate and / or a first downlink rate.

[0156] In some implementations, the first uplink rate and / or the first downlink rate are determined by the network device based on wireless conditions. For example, the network device determines the first uplink rate and / or the first downlink rate based on current wireless conditions.

[0157] In some implementations, if the first information includes a first uplink rate and / or a first downlink rate, the terminal device or the first network element may determine whether the first uplink rate and / or the first downlink rate is reasonable based on the above association relationship.

[0158] In some implementations, the terminal device or the first network element may determine whether the first uplink rate and / or the first downlink rate is reasonable based on the association relationship indicated by the first association information.

[0159] In some implementations, if the terminal device knows the first association information, whether the first uplink rate and / or the first downlink rate is reasonable is determined by the terminal device. That is, if the network device knows that the terminal device knows the first association information, the network device sends the first information to the terminal device, and the first information includes the first uplink rate and / or the first downlink rate. The terminal device determines whether the first uplink rate and / or the first downlink rate is reasonable based on the association relationship indicated by the first association information.

[0160] In some implementations, if the first gateway knows the first association information, whether the first uplink rate and / or the first downlink rate is reasonable is judged by the first network element, that is, if the network device knows that the first network element knows the first association information, the network device sends the first information to the first network element, and the first information includes the first uplink rate and / or the first downlink rate. The first network element judges whether the first uplink rate and / or the first downlink rate is reasonable based on the association relationship indicated by the first association information.

[0161] In some implementations, if the terminal device and the first network element are both aware of the first association information, whether the first uplink rate and / or the first downlink rate is reasonable is judged by either the terminal device or the first network element. That is, if the network device knows that the terminal device and the first network element are both aware of the first association information, the network device sends the first information to at least one of the terminal device and the first network element, and the first information includes the first uplink rate and / or the first downlink rate. The terminal device or the first network element judges whether the first uplink rate and / or the first downlink rate is reasonable based on the association relationship indicated by the first association information.

[0162] In some implementations, if the first network element knows the first association information, the network device sends the first information to the first network element, the first information includes the first uplink rate and / or the first downlink rate, and the first network element determines whether the first uplink rate and the first downlink rate are reasonable based on the association relationship indicated by the first association information.

[0163] In some implementations, if the terminal device knows the first association information, the network device sends the first information to the terminal device, the first information includes a first uplink rate and / or a first downlink rate, and the terminal device determines whether the first uplink rate and the first downlink rate are reasonable based on the association relationship indicated by the first association information.

[0164] In some implementations, if the terminal device and the first network element are both aware of the first association information, the network device sends the first information to any one of the terminal device and the first network element, the first information including the first uplink rate and / or the first downlink rate, and the terminal device or the first network element determines whether the first uplink rate and the first downlink rate are reasonable based on the association relationship indicated by the first association information.

[0165] In some implementations, if the first network element knows the first association information, the network device sends the first information to the terminal device and the first network element, the first information sent by the network device to the terminal device includes the uplink rate of the first service, the first information sent by the network device to the first network element includes the uplink rate of the first service and the first downlink rate, and the first network element determines whether the first downlink rate is reasonable based on the association relationship indicated by the first association information. In this way, the terminal device is less modified, which is conducive to implementation.

[0166] In some implementations, if the terminal device or the first network element determines that the first uplink rate and / or the first downlink rate is unreasonable, the uplink rate and / or downlink rate of the first service expected by the terminal device or the first network element is determined based on the first association information.

[0167] In some implementations, the uplink rate and / or downlink rate of the first service expected by the terminal device or the first network element can be understood as the uplink rate and / or downlink rate of the first service recommended by the terminal device or the first network element. For example, the terminal device gives a recommended downlink rate of the first service based on the channel quality measurement result and / or the first association information.

[0168] In some implementations, if the terminal device is aware of the first association information, the network device sends the first information to the terminal device and the first network element, the first information sent by the network device to the terminal device includes the first uplink rate and the downlink rate of the first service, the first information sent by the network device to the first network element includes the downlink rate of the first service, and the terminal device determines whether the first uplink rate is reasonable based on the association relationship indicated by the first association information.

[0169] In some implementations, if the terminal device and the first network element are both aware of the first association information, the network device may send the rate of its corresponding first service to either the terminal device or the first network element, and send the rate of its first service to be confirmed to the other. That is, the first information sent by the network device to the terminal device includes the uplink rate of the first service, and the first information sent to the first network element includes the uplink rate and the first downlink rate of the first service. The first network element determines whether the first downlink rate is reasonable based on the association relationship indicated by the first association information. Alternatively, the first information sent by the network device to the terminal device includes the downlink rate and the first uplink rate of the first service, and the first information sent to the first network element includes the downlink rate of the first service. The terminal device determines whether the first uplink rate is reasonable based on the association relationship indicated by the first association information.

[0170] In some implementations, if the first information includes a first uplink rate and a first downlink rate, judging whether the first uplink rate and / or the first downlink rate are reasonable can be understood as follows: if the first uplink rate and the first downlink rate satisfy an association relationship, the first uplink rate and the first downlink rate are reasonable; if the first uplink rate and the first downlink rate do not satisfy an association relationship, the first uplink rate and the first downlink rate are unreasonable. For example, the first association information refers to the three groups of uplink rates and downlink rates in Table 1. If the first uplink rate and the first downlink rate included in the first information are respectively the same as the uplink rate and the downlink rate indicated by any index in Table 1 (such as the first uplink rate is C, and the first downlink rate is C′), the first uplink rate and the first downlink rate are reasonable; if the first uplink rate and the first downlink rate included in the first information are not completely the same as the uplink rate and the downlink rate indicated by any index in Table 1 (such as the first uplink rate is not C and / or the first downlink rate is not C′), the first uplink rate and the first downlink rate are unreasonable. For another example, the first association information refers to the three groups of uplink rate ranges and downlink rate ranges in Table 2. If the first uplink rate and the first downlink rate included in the first information are respectively within the uplink rate range and the downlink rate range indicated by any index in Table 1 (such as the first uplink rate is within [C, D], and the first downlink rate is within [C′, D′]), then the first uplink rate and the first downlink rate are reasonable; if the first uplink rate and the first downlink rate included in the first information are not both within the uplink rate range and the downlink rate range indicated by any index in Table 1 (such as the first uplink rate is within [C, D], but the first downlink rate is not within [C′, D′]), then the first uplink rate and the first downlink rate are unreasonable.

[0171] In some implementations, if the first uplink rate and the first downlink rate are reasonable, the first uplink rate is the uplink rate of the first service, and the first downlink rate is the downlink rate of the first service.

[0172] In some implementations, if the first uplink rate and the first downlink rate are unreasonable, the terminal device or the first network element determines the uplink rate and downlink rate of the expected first service based on the first association information. For example, the first association information shows the three groups of uplink rates and downlink rates in Table 1. If the terminal device determines that the first uplink rate and the first downlink rate are unreasonable, a group of uplink rates and downlink rates are selected from the three groups in Table 1 as the uplink rate and downlink rate of the first service expected by the terminal device. Or select a rate pair in Table 1 in which the uplink rate is the same as the first uplink rate or the downlink rate is the same as the first downlink rate, and use the other rate as the other side rate of the first service expected by the terminal device. If the uplink rate with an index value of 1 in Table 1 is the same as the first downlink rate, the downlink rate with an index value of 1 is selected as the downlink rate of the first service expected by the terminal device. For another example, the first association information includes three groups of uplink rate ranges and downlink rate ranges in Table 2. If the terminal device determines that the first uplink rate and the first downlink rate are unreasonable, then one group of uplink rate ranges and downlink rate ranges are selected from the three groups in Table 2, and the uplink rate and downlink rate of the first service expected by the terminal device are selected from them. Alternatively, a rate range pair in Table 2 is selected in which the first uplink rate is within the uplink rate range or the first downlink rate is within the downlink rate range, and the other side rate of the first service expected by the terminal device is selected from the other rate range. For example, if the first downlink rate is within the downlink rate range with an index value of 1 in Table 2, then the uplink rate of the first service expected by the terminal device is selected from the uplink rate range with an index value of 1.

[0173] In some implementations, if the first information includes a first uplink rate, judging whether the first uplink rate is reasonable can be understood as follows: if the first uplink rate and the saved downlink rate of the first service satisfy an association relationship, the first uplink rate is reasonable; if the first uplink rate and the saved downlink rate of the first service do not satisfy an association relationship, the first uplink rate is unreasonable. For example, the first association information refers to the three groups of uplink rates and downlink rates in Table 1. If the first uplink rate and the saved downlink rate of the first service included in the first information are respectively the same as the uplink rate and downlink rate indicated by any index in Table 1 (such as the first uplink rate is C, and the saved downlink rate of the first service is C′), the first uplink rate is reasonable; if the first uplink rate and the saved downlink rate of the first service included in the first information are not completely the same as the uplink rate and downlink rate indicated by any index in Table 1 (such as the first uplink rate is not C and / or the saved downlink rate of the first service is not C′), the first uplink rate is unreasonable. For another example, the first association information refers to the three groups of uplink rate ranges and downlink rate ranges in Table 2. If the first uplink rate included in the first information and the saved downlink rate of the first service are respectively within the uplink rate range and the downlink rate range indicated by any index in Table 1 (such as the first uplink rate is within [C, D], and the saved downlink rate of the first service is within [C′, D′]), then the first uplink rate is reasonable; if the first uplink rate included in the first information and the saved downlink rate of the first service are not both within the uplink rate range and the downlink rate range indicated by any index in Table 1 (such as the first uplink rate is within [C, D], but the saved downlink rate of the first service is not within [C′, D′]), then the first uplink rate is unreasonable.

[0174] In some implementations, if the first uplink rate is reasonable, the first uplink rate is the uplink rate of the first service.

[0175] In some implementations, if the first uplink rate is unreasonable, the terminal device or the first network element determines the expected uplink rate of the first service based on the first association information. For example, the first association information is shown in the three groups of uplink rates and downlink rates in Table 1. If the terminal device determines that the first uplink rate is unreasonable, select a rate pair in Table 1 whose downlink rate is the same as the saved downlink rate of the first service, and use the uplink rate of the rate pair as the uplink rate of the first service expected by the terminal device. For another example, the first association information is shown in the three groups of uplink rate ranges and downlink rate ranges in Table 2. If the terminal device determines that the first uplink rate is unreasonable, select a rate range pair in which the saved downlink rate of the first service is within the range of the downlink rate from the three groups in Table 2, and select a rate from the range of the uplink rate of the rate range pair as the uplink rate of the first service expected by the terminal device.

[0176] In some implementations, if the first information includes a first downlink rate, judging whether the first downlink rate is reasonable can be understood as follows: if the first downlink rate and the uplink rate of the first service saved satisfy an association relationship, the first downlink rate is reasonable; if the first downlink rate and the uplink rate of the first service saved do not satisfy an association relationship, the first downlink rate is unreasonable. For example, the first association information refers to the three groups of uplink rates and downlink rates in Table 1. If the first downlink rate included in the first information and the uplink rate of the first service saved are respectively the same as the uplink rate and downlink rate indicated by any index in Table 1 (such as the uplink rate of the first service saved is C, and the first downlink rate is C′), the first downlink rate is reasonable; if the first downlink rate included in the first information and the uplink rate of the first service saved are not completely the same as the uplink rate and downlink rate indicated by any index in Table 1 (such as the uplink rate of the first service saved is not C and / or the first downlink rate is not C′), the first downlink rate is unreasonable. For another example, the first associated information refers to the three groups of uplink rate ranges and downlink rate ranges in Table 2. If the first downlink rate included in the first information and the saved uplink rate of the first service are respectively within the uplink rate range and the downlink rate range indicated by any index in Table 1 (such as the saved uplink rate of the first service is within [C, D], and the first downlink rate is within [C′, D′]), then the first downlink rate is reasonable; if the first downlink rate included in the first information and the saved uplink rate of the first service are not both within the uplink rate range and the downlink rate range indicated by any index in Table 1 (such as the saved uplink rate of the first service is within [C, D], but the first downlink rate is not within [C′, D′]), then the first downlink rate is unreasonable.

[0177] In some implementations, if the first downlink rate is reasonable, the first downlink rate is the downlink rate of the first service.

[0178] In some implementations, if the first downlink rate is unreasonable, the terminal device or the first network element determines the expected downlink rate of the first service based on the first association information. For example, the first association information is shown in the three groups of uplink rates and downlink rates in Table 1. If the terminal device determines that the first downlink rate is unreasonable, select a rate pair in Table 1 whose uplink rate is the same as the uplink rate of the saved first service, and use the downlink rate of the rate pair as the downlink rate of the first service expected by the terminal device. For another example, the first association information is shown in the three groups of uplink rate ranges and downlink rate ranges in Table 2. If the terminal device determines that the first downlink rate is unreasonable, select a rate range pair in which the uplink rate of the saved first service is within the range of the uplink rate from the three groups in Table 2, and select a rate from the range of downlink rates of the rate range pair as the downlink rate of the first service expected by the terminal device.

[0179] In some implementations, if the first information includes the uplink rate and the first downlink rate of the first service, judging whether the first downlink rate is reasonable can be understood as follows: if the uplink rate and the first downlink rate of the first service satisfy the association relationship, the first uplink rate is reasonable; if the uplink rate and the first downlink rate of the first service do not satisfy the association relationship, the first downlink rate is unreasonable. For example, the first association information refers to the three groups of uplink rates and downlink rates in Table 1. If the uplink rate and the first downlink rate of the first service included in the first information are respectively the same as the uplink rate and the downlink rate indicated by any index in Table 1 (such as the uplink rate of the first service is C, and the first downlink rate is C′), the first downlink rate is reasonable; if the uplink rate and the first downlink rate of the first service included in the first information are not completely the same as the uplink rate and the downlink rate indicated by any index in Table 1 (such as the uplink rate of the first service is not C and / or the first downlink rate is not C′), the first downlink rate is unreasonable. For another example, the first associated information refers to the three groups of uplink rate ranges and downlink rate ranges in Table 2. If the uplink rate and the first downlink rate of the first service included in the first information are respectively within the uplink rate range and the downlink rate range indicated by any index in Table 1 (such as the uplink rate of the first service is within [c, D], and the first downlink rate is within [C′, D′]), then the first downlink rate is reasonable; if the uplink rate and the first downlink rate of the first service included in the first information are not both within the uplink rate range and the downlink rate range indicated by any index in Table 1 (such as the uplink rate of the first service is within [C, D], but the first downlink rate is not within [C′, D′]), then the first downlink rate is unreasonable.

[0180] In some implementations, if the first downlink rate is reasonable, the first downlink rate is the downlink rate of the first service.

[0181] In some implementations, if the first downlink rate is unreasonable, the terminal device or the first network element determines the expected downlink rate of the first service based on the first association information. For example, the first association information is shown in the three groups of uplink rates and downlink rates in Table 1. If the terminal device determines that the first downlink rate is unreasonable, select a rate pair in Table 1 whose uplink rate is the same as the uplink rate of the first service, and use the downlink rate of the rate pair as the downlink rate of the first service expected by the terminal device. For another example, the first association information is shown in the three groups of uplink rate ranges and downlink rate ranges in Table 2. If the terminal device determines that the first downlink rate is unreasonable, select a rate range pair in which the uplink rate of the first service is within the range of the uplink rate from the three groups in Table 2, and select a rate from the range of downlink rates of the rate range pair as the downlink rate of the first service expected by the terminal device.

[0182] In some implementations, if the first information includes the downlink rate and the first uplink rate of the first service, judging whether the first uplink rate is reasonable can be understood as follows: if the downlink rate of the first service and the first uplink rate satisfy the association relationship, the first uplink rate is reasonable; if the downlink rate of the first service and the first uplink rate do not satisfy the association relationship, the first uplink rate is unreasonable. For example, the first association information refers to the three groups of uplink rates and downlink rates in Table 1. If the first uplink rate and the downlink rate of the first service included in the first information are respectively the same as the uplink rate and the downlink rate indicated by any index in Table 1 (such as the first uplink rate is C, and the downlink rate of the first service is C′), the first uplink rate is reasonable; if the first uplink rate and the downlink rate of the first service included in the first information are not completely the same as the uplink rate and the downlink rate indicated by any index in Table 1 (such as the first uplink rate is not C and / or the downlink rate of the first service is not C′), the first uplink rate is unreasonable. For another example, the first association information refers to the three groups of uplink rate ranges and downlink rate ranges in Table 2. If the first uplink rate and the downlink rate of the first service included in the first information are respectively within the uplink rate range and the downlink rate range indicated by any index in Table 1 (such as the first uplink rate is within [C, D], and the downlink rate of the first service is within [C′, D′]), then the first uplink rate is reasonable; if the first uplink rate and the downlink rate of the first service included in the first information are not both within the uplink rate range and the downlink rate range indicated by any index in Table 1 (such as the first uplink rate is within [C, D], but the downlink rate of the first service is not within [C′, D′]), then the first uplink rate is unreasonable.

[0183] In some implementations, if the first uplink rate is reasonable, the first uplink rate is the uplink rate of the first service.

[0184] In some implementations, if the first uplink rate is unreasonable, the terminal device or the first network element determines the expected uplink rate of the first service based on the first associated information. For example, the first associated information is shown in the three groups of uplink rates and downlink rates in Table 1. If the terminal device determines that the first uplink rate is unreasonable, select a rate pair in Table 1 whose downlink rate is the same as the downlink rate of the first service, and use the uplink rate of the rate pair as the uplink rate of the first service expected by the terminal device. For another example, the first associated information is shown in the three groups of uplink rate ranges and downlink rate ranges in Table 2. If the terminal device determines that the first uplink rate is unreasonable, select a rate range pair in which the downlink rate of the first service is within the range of the downlink rate from the three groups in Table 2, and select a rate from the range of the uplink rate of the rate range pair as the uplink rate of the first service expected by the terminal device.

[0185] In some implementations, after the terminal device or the network device determines whether the first uplink rate and / or the first downlink rate is reasonable, the terminal device or the first network element sends a response message to the network device.

[0186] In some implementations, the response information is used to indicate one or more of the following: whether the first uplink rate is the uplink rate of the first service; whether the first downlink rate is the downlink rate of the first service; the uplink rate and / or downlink rate of the first service expected by the terminal device or the first network element; and the network device re-initiating rate adjustment of the first service.

[0187] In some implementations, if the terminal device or the first network element determines that the first uplink rate is reasonable, the response information indicates that the first uplink rate is the uplink rate of the first service.

[0188] In some implementations, if the terminal device or the first network element determines that the first uplink rate is unreasonable, the response information indicates that the first uplink rate is not the uplink rate of the first service.

[0189] In some implementations, if the terminal device or the first network element determines that the first uplink rate is unreasonable, the response information indicates the uplink rate of the first service expected by the terminal device or the first network element.

[0190] In some implementations, if the terminal device or the first network element determines that the first downlink rate is reasonable, the response information indicates that the first downlink rate is the uplink rate of the first service.

[0191] In some implementations, if the terminal device or the first network element determines that the first downlink rate is unreasonable, the response information indicates that the first downlink rate is not the downlink rate of the first service.

[0192] In some implementations, if the terminal device or the first network element determines that the first downlink rate is unreasonable, the response information indicates the downlink rate of the first service expected by the terminal device or the first network element.

[0193] In some implementations, if the terminal device or the first network element determines that the first uplink rate and the first downlink rate are reasonable, the response information indicates that the first uplink rate is the uplink rate of the first service, and the first downlink rate is the downlink rate of the first service.

[0194] In some implementations, if the terminal device or the first network element determines that the first uplink rate and the first downlink rate are unreasonable, the response information indicates that the first uplink rate is not the uplink rate of the first service, and the first downlink rate is not the downlink rate of the first service.

[0195] In some implementations, if the terminal device or the first network element determines that the first uplink rate and the first downlink rate are unreasonable, the response information indicates the uplink rate and downlink rate of the first service expected by the terminal device or the first network element.

[0196] In some implementations, if the terminal device or the first network element determines that the first uplink rate and / or the first downlink rate is unreasonable, the response information is also used to instruct the network device to re-initiate rate adjustment of the first service.

[0197] In some implementations, the response information sent by the terminal device to the network device is carried in a MAC CE or RRC message.

[0198] In some implementations, the response information sent by the first network element to the network device is carried in an NG interface message.

[0199] It should be noted that the method for sending the first information is also applicable to the response information. For details, please refer to the description of the method for sending the first information in the above text, which will not be repeated here.

[0200] In some implementations, if the first information sent by the network device to the first network element includes the first uplink rate and / or the first downlink rate, and the response information indicates that the first uplink rate is the uplink rate of the first service, then after receiving the response information, if the uplink rate of the first service indicated by the response information is different from the uplink rate of the current first service, the network device sends the first information to the terminal device, and the first information includes the uplink rate of the first service. If the uplink rate of the first service indicated by the response information is the same as the uplink rate of the current first service, the first information is not sent to the terminal device. The network device first notifies the first network element of the first information, and the terminal device does not need to know the first associated information, which helps to reduce the information flow of air interface transmission.

[0201] In some implementations, if the first information sent by the network device to the first network element includes a first uplink rate and / or a first downlink rate, and the response information indicates the uplink rate of the first service expected by the first network element, then after receiving the response information, if the uplink rate of the first service expected by the first network element indicated by the response information is different from the uplink rate of the current first service, and the network device recognizes the uplink rate of the first service expected by the first network element, the network device sends the first information to the terminal device, the first information including the uplink rate of the first service, and the uplink rate of the first service is the uplink rate of the first service expected by the first network element; if the uplink rate of the first service expected by the first network element indicated by the response information is the same as the uplink rate of the current first service, the first information is not sent to the terminal device.

[0202] In some implementations, if the first information sent by the network device to the terminal device includes the first uplink rate and / or the first downlink rate, and the response information indicates that the first downlink rate is the downlink rate of the first service, then after receiving the response information, if the downlink rate of the first service indicated by the response information is different from the current downlink rate of the first service, the network device sends the first information to the first network element, and the first information includes the downlink rate of the first service. If the downlink rate of the first service indicated by the response information is the same as the current downlink rate of the first service, the first information is not sent to the first network element. The network device first notifies the terminal device of the first information. Due to the fast air interface information interaction, the uplink rate of the first service of the terminal device can be quickly adjusted, which helps to quickly relieve congestion when the network is congested.

[0203] In some implementations, if the first information sent by the network device to the terminal device includes a first uplink rate and / or a first downlink rate, and the response information indicates the downlink rate of the first service expected by the terminal device, then after receiving the response information, if the downlink rate of the first service expected by the terminal device indicated in the response information is different from the current downlink rate of the first service, and the network device recognizes the uplink rate of the first service expected by the terminal device, the network device sends the first information to the first network element, the first information including the downlink rate of the first service, and the downlink rate of the first service is the downlink rate of the first service expected by the terminal device; if the downlink rate of the first service expected by the terminal device indicated in the response information is the same as the current downlink rate of the first service, the first information is not sent to the first network element.

[0204] In some implementations, if the response information instructs the network device to re-initiate rate adjustment of the first service, the network device may re-initiate a new round of rate adjustment of the first service after receiving the response information to determine a reasonable uplink rate and / or downlink rate of the first service.

[0205] For ease of understanding, the following takes the example of the network device knowing the first network element known first association information. Figure 5 This section introduces the solution for implementing method 2-1. Figure 5 Includes steps S510 to S540.

[0206] Assume that the first service is an XR service, the network device is an access network device, the access network device sends the first information to the first network element through the core network network element, the first network element is an XR server, the access network device is a gNB, and the core network network elements include SMF and AMF.

[0207] In step S510, the gNB sends first information to the XR server.

[0208] The gNB notifies the AMF of the first information through the NG interface message, and then forwards it through the SMF to notify the XR server of the first information. The first information includes the first uplink rate and the first downlink rate.

[0209] In step S520, the XR server determines whether the first uplink rate and the first downlink rate are reasonable.

[0210] The XR server determines whether the first uplink rate and the first downlink rate are reasonable based on the first association information. Specifically, if the first uplink rate and the first downlink rate satisfy the association relationship indicated by the first association information, then the first uplink rate and the first downlink rate are reasonable, and the first uplink rate is the uplink rate of the XR service, and the first downlink rate is the downlink rate of the XR service.

[0211] In step S530, the XR server sends a response message to the gNB.

[0212] The response information sent by the XR server to the gNB indicates that the first uplink rate is the uplink rate of the XR service, and the first downlink rate is the downlink rate of the XR service.

[0213] In step S540, the gNB sends first information to the terminal device.

[0214] After receiving the response information and determining the uplink rate of the XR service, the gNB sends the first information to the terminal device through an RRC message. The RRC layer of the terminal device receives the first information and notifies the application layer of the terminal device. The first information includes the uplink rate of the XR service.

[0215] Implementation method 2-2: The first information includes a first uplink rate range and / or a first downlink rate range.

[0216] In some implementations, if the first information includes a first uplink rate range and / or a first downlink rate range, the terminal device or the first network element selects the uplink rate and / or downlink rate of the first service from the first uplink rate range and / or the first downlink rate range based on the association relationship.

[0217] In some implementations, if the first network element knows the first association information, the network device sends the first information to the first network element, the first information includes a first uplink rate range and / or a first downlink rate range, and the first network element selects the uplink rate and / or downlink rate of the first service from the first uplink rate range and / or the first downlink rate range based on the association relationship indicated by the first association information.

[0218] In some implementations, if the terminal device knows the first association information, the network device sends the first information to the terminal device, the first information includes a first uplink rate range and / or a first downlink rate range, and the terminal device selects the uplink rate and / or downlink rate of the first service from the first uplink rate range and / or the first downlink rate range based on the association relationship indicated by the first association information.

[0219] In some implementations, if the terminal device and the first network element are both aware of the first association information, the network device sends the first information to any one of the terminal device and the first network element, the first information including a first uplink speed range and / or a first downlink rate range, and the terminal device or the first network element selects the uplink rate and / or downlink rate of the first service from the first uplink rate range and / or the first downlink rate range based on the association relationship indicated by the first association information.

[0220] In some implementations, if the first network element knows the first association information, the network device sends the first information to the terminal device and the first network element, the first information sent by the network device to the terminal device includes the uplink rate of the first service, the first information sent by the network device to the first network element includes the uplink rate of the first service and a first downlink rate range, and the first network element selects the downlink rate of the first service from the first downlink rate range based on the association relationship indicated by the first association information.

[0221] In some implementations, if the terminal device knows the first association information, the network device sends the first information to the terminal device and the first network element, the first information sent by the network device to the terminal device includes the first uplink rate range and the downlink rate of the first service, the first information sent by the network device to the first network element includes the downlink rate of the first service, and the terminal device selects the uplink rate of the first service from the first uplink rate range based on the association relationship indicated by the first association information.

[0222] In some implementations, if the terminal device and the first network element are both aware of the first association information, the network device may send the rate of the corresponding first service to either the terminal device or the first network element, and send the rate range of the first service to be confirmed to the other. That is, the first information sent by the network device to the terminal device includes the uplink rate of the first service, and the first information sent to the first network element includes the uplink rate of the first service and the first downlink rate range. The first network element selects the downlink rate of the first service from the first downlink rate range based on the association relationship indicated by the first association information. Alternatively, the first information sent by the network device to the terminal device includes the downlink rate of the first service and the first uplink rate range. The first information sent to the first network element includes the downlink rate of the first service. The terminal device selects the uplink rate of the first service from the first uplink rate range based on the association relationship indicated by the first association information.

[0223] In some implementations, if the first information includes a first uplink rate range and a first downlink rate range, the terminal device or the first network element selects the uplink rate and downlink rate of the first service from the first uplink rate range and the first downlink rate range based on the association relationship.

[0224] In some implementations, based on the association relationship, the uplink rate and downlink rate of the first service are selected from the first uplink rate range and the first downlink rate range. It can be understood that the uplink rate and downlink rate of the first service that satisfy the association relationship indicated by the first association information are selected from the first uplink rate range and the first downlink rate range.

[0225] In some implementations, if the first association information includes an uplink rate and / or a downlink rate, then the uplink rate and downlink rate of the first service that satisfy the association relationship indicated by the first association information are selected from the first uplink rate range and the first downlink rate range. It can be understood that, from the multiple groups of uplink rates and downlink rates indicated by the first association information, a rate pair that is both within the first uplink rate range and the first downlink rate range is selected as the uplink rate and downlink rate of the first service. For example, the first association information includes an uplink rate and a first ratio. The first association information refers to the three groups of uplink rates and first ratios in Table 3. Table 3 indicates three groups of uplink rates and downlink rates. From the three groups of uplink rates and downlink rates, a rate pair that is both within the first uplink rate range and the first downlink rate range is selected as the uplink rate and downlink rate of the first service.

[0226] In some implementations, if the first association information includes an uplink rate range and / or a downlink rate range, then the uplink rate and downlink rate of the first service that satisfies the association relationship indicated by the first association information are selected from the first uplink rate range and the first downlink rate range. This can be understood as selecting the uplink rate and downlink rate of the first service from the intersection of the multiple groups of uplink rate ranges and downlink rate ranges indicated by the first association information and the first uplink rate range and the first downlink rate range. For example, if the first association information is the three groups of uplink rate ranges and downlink rate ranges in Table 2, the uplink rate and downlink rate of the first service are selected from the intersection of the three groups of uplink rate ranges and downlink rate ranges and the first uplink rate range and the first downlink rate range.

[0227] In some implementations, if the first information includes a first downlink rate range, and the first information also includes an uplink rate of the first service, the terminal device selects the downlink rate of the first service from the first downlink rate range based on the association relationship. It can be understood that if the first information includes the uplink rate of the first service and the first downlink rate range, the terminal device selects the downlink rate of the first service from the first downlink rate range that satisfies the association relationship with the uplink rate of the first service.

[0228] In some implementations, if the first association information includes an uplink rate and / or a downlink rate, then the downlink rate of the first service that satisfies the association relationship with the uplink rate of the first service is selected from the first downlink rate range. It can be understood that, from the multiple groups of uplink rates and downlink rates indicated by the first association information, a rate pair whose uplink rate is the same as the uplink rate of the first service and whose downlink rate is within the first downlink rate range is selected, and the downlink rate is used as the downlink rate of the first service. For example, the first association information includes an uplink rate and a first ratio. The first association information is shown in Table 3, which indicates three groups of uplink rates and downlink rates. From the three groups of uplink rates and downlink rates, a rate pair whose uplink rate is the same as the uplink rate of the first service and whose downlink rate is within the first downlink rate range is selected, and the downlink rate is used as the downlink rate of the first service.

[0229] In some implementations, if the first association information includes an uplink rate range and / or a downlink rate range, then the downlink rate of the first service that satisfies the association relationship with the uplink rate of the first service is selected from the first downlink rate range. It can be understood that, from the multiple groups of uplink rate ranges and downlink rate ranges indicated by the first association information, a rate range pair is selected in which the uplink rate of the first service is within the uplink rate range, and the downlink rate range and the first downlink rate range have an intersection, and the downlink rate of the first service is selected from the intersection of the downlink rate range and the first downlink rate range. For example, the first association information refers to Table 2, which indicates three groups of uplink rate ranges and downlink rate ranges. From the three groups of uplink rate ranges and downlink rate ranges, a rate range pair is selected in which the uplink rate of the first service is within the uplink rate range, and the downlink rate range and the first downlink rate range have an intersection, and the downlink rate of the first service is selected from the intersection of the downlink rate range in the rate range pair and the first downlink rate range.

[0230] In some implementations, if the first information includes a first uplink rate range, and the first information also includes a downlink rate of the first service, the first network element selects the uplink rate of the first service from the first uplink rate range based on the association relationship. It can be understood that if the first information includes the downlink rate of the first service and the first uplink rate range, the first network element selects the uplink rate of the first service from the first uplink rate range that satisfies the association relationship with the downlink rate of the first service.

[0231] In some implementations, if the first association information includes an uplink rate and / or a downlink rate, then the uplink rate of the first service that satisfies the association relationship with the downlink rate of the first service is selected from the first uplink rate range. It can be understood that, from the multiple groups of uplink rates and downlink rates indicated by the first association information, a rate pair whose downlink rate is the same as the downlink rate of the first service and whose uplink rate is within the first uplink rate range is selected, and the uplink rate is used as the uplink rate of the first service. For example, the first association information includes an uplink rate and a first ratio. The first association information is shown in Table 3, which indicates three groups of uplink rates and downlink rates. From the three groups of uplink rates and downlink rates, a rate pair whose downlink rate is the same as the downlink rate of the first service and whose uplink rate is within the first uplink rate range is selected, and the uplink rate is used as the uplink rate of the first service.

[0232] In some implementations, if the first association information includes an uplink rate range and / or a downlink rate range, then the uplink rate of the first service that satisfies the association relationship with the downlink rate of the first service is selected from the first uplink rate range. It can be understood that, from the multiple groups of uplink rate ranges and downlink rate ranges indicated by the first association information, a rate range pair is selected in which the downlink rate of the first service is within the range of the downlink rate, and the uplink rate range and the first uplink rate range have an intersection, and the uplink rate of the first service is selected from the intersection of the uplink rate range and the first uplink rate range. For example, the first association information refers to Table 2, which indicates three groups of uplink rate ranges and downlink rate ranges. From the three groups of uplink rate ranges and downlink rate ranges, a rate range pair is selected in which the downlink rate of the first service is within the range of the downlink rate, and the uplink rate range and the first uplink rate range have an intersection, and the uplink rate of the first service is selected from the intersection of the uplink rate range in the rate range pair and the first uplink rate range.

[0233] In some implementations, if the first information includes a first uplink rate range, the terminal device or the first network element selects the uplink rate of the first service from the first uplink rate range based on the association relationship. It can be understood that the terminal device or the first network element selects the uplink rate of the first service from the first uplink rate range that satisfies the association relationship indicated by the first association information with the saved downlink rate of the first service.

[0234] In some implementations, if the first association information includes an uplink rate and / or a downlink rate, then from the first uplink rate range, the uplink rate of the first service that satisfies the association relationship indicated by the first association information with the downlink rate of the first service that is saved is selected. It can be understood that, from the multiple groups of uplink rates and downlink rates indicated by the first association information, a rate pair whose uplink rate is within the first uplink rate range and whose downlink rate is the same as the saved downlink rate of the first service is selected, and the uplink rate is used as the uplink rate of the first service. For example, the first association information includes an uplink rate and a first ratio. The first association information refers to the three groups of uplink rates and first ratios in Table 3. Table 3 indicates three groups of uplink rates and downlink rates. From the three groups of uplink rates and downlink rates, a rate pair whose uplink rate is within the first uplink rate range and whose downlink rate is the same as the saved downlink rate of the first service is selected, and the uplink rate is used as the uplink rate of the first service.

[0235] In some implementations, if the first association information includes an uplink rate range and / or a downlink rate range, then from the first uplink rate range, the uplink rate of the first service that satisfies the association relationship indicated by the first association information with the downlink rate of the first service is selected. This can be understood as selecting a rate range pair in which the downlink rate of the first service is within the range of the downlink rate and the uplink rate range intersects with the first uplink rate range from the multiple groups of uplink rate ranges and downlink rate ranges indicated by the first association information, and selecting the uplink rate of the first service from the intersection of the uplink rate range and the first uplink rate range. For example, the first association information is three groups of uplink rate ranges and downlink rate ranges in Table 2, and from the three groups of uplink rate ranges and downlink rate ranges, a rate range pair in which the downlink rate of the first service is within the range of the downlink rate and the uplink rate range intersects with the first uplink rate range is selected, and the uplink rate of the first service is selected from the intersection of the uplink rate range in the rate range pair and the first uplink rate range.

[0236] In some implementations, if the first information includes a first downlink rate range, the terminal device or the first network element selects the downlink rate of the first service from the first downlink rate range based on the association relationship. It can be understood that the terminal device or the first network element selects the downlink rate of the first service from the first downlink rate range that satisfies the association relationship indicated by the first association information with the saved uplink rate of the first service.

[0237] In some implementations, if the first association information includes an uplink rate and / or a downlink rate, then from the first downlink rate range, the downlink rate of the first service that satisfies the association relationship indicated by the first association information with the uplink rate of the saved first service is selected. It can be understood that, from the multiple groups of uplink rates and downlink rates indicated by the first association information, a rate pair whose downlink rate is within the first downlink rate range and whose uplink rate is the same as the uplink rate of the saved first service is selected, and the downlink rate is used as the downlink rate of the first service. For example, the first association information includes an uplink rate and a first ratio. The first association information refers to the three groups of uplink rates and first ratios in Table 3. Table 3 indicates three groups of uplink rates and downlink rates. From the three groups of uplink rates and downlink rates, a rate pair whose downlink rate is within the first downlink rate range and whose uplink rate is the same as the uplink rate of the saved first service is selected, and the downlink rate is used as the downlink rate of the first service.

[0238] In some implementations, if the first association information includes an uplink rate range and / or a downlink rate range, then from the first downlink rate range, the downlink rate of the first service that satisfies the association relationship indicated by the first association information with the uplink rate of the saved first service is selected. This can be understood as selecting a rate range pair in which the uplink rate of the saved first service is within the uplink rate range and the downlink rate range intersects with the first downlink rate range from the multiple groups of uplink rate ranges and downlink rate ranges indicated by the first association information, and selecting the downlink rate of the first service from the intersection of the downlink rate range and the first downlink rate range. For example, the first association information is three groups of uplink rate ranges and downlink rate ranges in Table 2, and from the three groups of uplink rate ranges and downlink rate ranges, a rate range pair in which the uplink rate of the saved first service is within the uplink rate range and the downlink rate range intersects with the first downlink rate range is selected, and the downlink rate of the first service is selected from the intersection of the downlink rate range in the rate range pair and the first downlink rate range.

[0239] In some implementations, if a terminal device or a first network element selects an uplink rate and a downlink rate of a first service that satisfies an association relationship from a first uplink rate range and a first downlink rate range, the terminal device or the first network element may send a response message to the network device, and the response message is used to indicate the uplink rate and the downlink rate of the first service.

[0240] In some implementations, if the terminal device or the first network element does not select the uplink rate and downlink rate of the first service that satisfy the association relationship from the first uplink rate range and the first downlink rate range, the terminal device or the first network element may send a response message to the network device, and the response message is used to instruct the network device to re-initiate rate adjustment of the first service.

[0241] In some implementations, if the terminal device or the first network element does not select the uplink rate and downlink rate of the first service that meets the association relationship from the first uplink rate range and the first downlink rate range, the terminal device or the first network element determines the uplink rate and downlink rate of the first service that it expects based on the first association information, and sends a response message to the network device, where the response message indicates the uplink rate and downlink rate of the first service that the terminal device or the first network element expects. For example, the first association information shows the three groups of uplink rates and downlink rates in Table 1. If the terminal device does not select the uplink rate and downlink rate of the first service that meets the association relationship, a group of uplink rates or downlink rates is selected from the three groups in Table 1 as the uplink rate and downlink rate of the first service that the terminal device expects. Alternatively, a rate pair in which the uplink rate is within the first uplink rate range or the downlink rate is within the first downlink rate range in Table 1 is selected, and the uplink rate and downlink rate in the rate pair are used as the uplink rate and downlink rate of the first service that the terminal device expects. For another example, the first association information includes three groups of uplink rate ranges and downlink rate ranges in Table 2. If the terminal device does not select the uplink rate and downlink rate of the first service that satisfy the association relationship, then a group of uplink rate ranges and downlink rate ranges are selected from the three groups in Table 2, and the uplink rate and downlink rate of the first service expected by the terminal device are selected from them. Alternatively, a rate range pair is selected in which the uplink rate range in Table 2 intersects with the first uplink rate range or the downlink rate range intersects with the first downlink rate range, and one side rate of the first service expected by the terminal device is selected from the intersection of the above ranges, and the other side rate of the first service expected by the terminal device is selected from the other rate range of the rate range pair. For example, if the first downlink rate range intersects with the downlink rate range with an index value of 1 in Table 2, then the downlink rate of the first service expected by the terminal device is selected from the intersection of the downlink rate range with an index value of 1 and the first downlink rate range, and the uplink rate of the first service expected by the terminal device is selected from the uplink rate range of the rate range pair.

[0242] In some implementations, if the terminal device or the first network element selects a downlink rate of the first service from the first downlink rate range that satisfies the association relationship with the uplink rate of the first service, the terminal device or the first network element sends a response message to the network device, and the response information is used to indicate the downlink rate of the first service.

[0243] In some implementations, if the terminal device or the first network element does not select a downlink rate of the first service that satisfies the association relationship with the uplink rate of the first service from the first downlink rate range, the terminal device or the first network element sends a response message to the network device, and the response message is used to instruct the network device to re-initiate rate adjustment of the first service.

[0244] In some implementations, if the terminal device or the first network element does not select a downlink rate of the first service that satisfies an association relationship with the uplink rate of the first service from the first downlink rate range, the terminal device or the first network element determines the downlink rate of the first service it expects based on the first association information, and sends a response message to the network device, where the response message is used to indicate the downlink rate of the first service that the terminal device or the first network element expects. For example, the first association information is shown in the three groups of uplink rates and downlink rates in Table 1. If the terminal device does not select a downlink rate of the first service that satisfies an association relationship with the uplink rate of the first service, a rate pair in Table 1 with the same uplink rate as the uplink rate of the first service is selected, and the downlink rate of the rate pair is used as the downlink rate of the first service that the terminal device expects. For another example, the first association information includes three groups of uplink rate ranges and downlink rate ranges in Table 2. If the terminal device does not select a downlink rate of the first service that satisfies the association relationship with the uplink rate of the first service, a rate range pair in which the uplink rate of the first service is within the range of the uplink rate is selected from the three groups in Table 2, and a rate is selected from the range of the downlink rate of the rate range pair as the downlink rate of the first service expected by the terminal device.

[0245] In some implementations, if the terminal device or the first network element selects an uplink rate of the first service from the first uplink rate range that satisfies the correlation relationship with the downlink rate of the first service, the terminal device or the first network element sends a response message to the network device, and the response information is used to indicate the uplink rate of the first service.

[0246] In some implementations, if the terminal device or the first network element does not select an uplink rate of the first service that satisfies an association relationship with the downlink rate of the first service from the first uplink rate range, the terminal device or the first network element sends a response message to the network device, and the response message is used to instruct the network device to re-initiate rate adjustment of the first service.

[0247] In some implementations, if the terminal device or the first network element does not select an uplink rate of the first service that satisfies an association relationship with the downlink rate of the first service from the first uplink rate range, the terminal device or the first network element determines the downlink rate of the first service it expects based on the first association information, and sends a response message to the network device, where the response message is used to indicate the uplink rate of the first service that the terminal device or the first network element expects. For example, the first association information is shown in the three groups of uplink rates and downlink rates in Table 1. If the terminal device does not select an uplink rate of the first service that satisfies an association relationship with the downlink rate of the first service, a rate pair in Table 1 whose downlink rate is the same as the downlink rate of the first service is selected, and the uplink rate of the rate pair is used as the uplink rate of the first service that the terminal device expects. For another example, the first association information includes three groups of uplink rate ranges and downlink rate ranges in Table 2. If the terminal device does not select an uplink rate of the first service that satisfies the association relationship with the uplink rate of the first service, a rate range pair in which the downlink rate of the first service is within the range of the downlink rate is selected from the three groups in Table 2, and a rate is selected from the range of the uplink rate of the rate range pair as the uplink rate of the first service expected by the terminal device.

[0248] In some implementations, if the terminal device or the first network element selects a downlink rate of the first service from the first downlink rate range that satisfies the association relationship with the saved uplink rate of the first service, the terminal device or the first network element sends a response message to the network device, and the response information is used to indicate the downlink rate of the first service.

[0249] In some implementations, if the terminal device or the first network element does not select a downlink rate of the first service that satisfies the association relationship with the saved uplink rate of the first service from the first downlink rate range, the terminal device or the first network element sends a response message to the network device, and the response message is used to instruct the network device to re-initiate rate adjustment of the first service.

[0250] In some implementations, if the terminal device or the first network element does not select a downlink rate of the first service that satisfies an association relationship with the uplink rate of the saved first service from the first downlink rate range, the terminal device or the first network element determines the downlink rate of the first service it expects based on the first association information, and sends a response message to the network device, where the response message is used to indicate the downlink rate of the first service that the terminal device or the first network element expects. For example, the first association information is shown in three groups of uplink rates and downlink rates in Table 1. If the terminal device does not select a downlink rate of the first service that satisfies an association relationship with the uplink rate of the saved first service, a rate pair in Table 1 with the same uplink rate as the uplink rate of the saved first service is selected, and the downlink rate of the rate pair is used as the downlink rate of the first service that the terminal device expects. For another example, the first association information includes three groups of uplink rate ranges and downlink rate ranges in Table 2. If the terminal device does not select a downlink rate of the first service that satisfies the association relationship with the saved uplink rate of the first service, a rate range pair in which the uplink rate of the saved first service is within the range of the uplink rate is selected from the three groups in Table 2, and a rate is selected from the range of the downlink rate of the rate range pair as the downlink rate of the first service expected by the terminal device.

[0251] In some implementations, if the terminal device or the first network element selects an uplink rate of the first service from the first uplink rate range that satisfies the association relationship with the saved downlink rate of the first service, the terminal device or the first network element sends a response message to the network device, and the response information is used to indicate the uplink rate of the first service.

[0252] In some implementations, if the terminal device or the first network element does not select an uplink rate of the first service from the first uplink rate range that satisfies the association relationship with the saved downlink rate of the first service, the terminal device or the first network element sends a response message to the network device, and the response message is used to instruct the network device to re-initiate rate adjustment of the first service.

[0253] In some implementations, if the terminal device or the first network element does not select an uplink rate of the first service that satisfies an association relationship with the downlink rate of the saved first service from the first uplink rate range, the terminal device or the first network element determines the uplink rate of the first service it expects based on the first association information, and sends a response message to the network device, where the response message is used to indicate the uplink rate of the first service that the terminal device or the first network element expects. For example, the first association information is shown in the three groups of uplink rates and downlink rates in Table 1. If the terminal device does not select an uplink rate of the first service that satisfies an association relationship with the downlink rate of the saved first service, a rate pair in Table 1 whose downlink rate is the same as the downlink rate of the saved first service is selected, and the uplink rate of the rate pair is used as the uplink rate of the first service that the terminal device expects. For another example, the first association information includes three groups of uplink rate ranges and downlink rate ranges in Table 2. If the terminal device does not select an uplink rate of the first service that satisfies the association relationship with the saved downlink rate of the first service, a rate range pair in which the downlink rate of the saved first service is within the range of the downlink rate is selected from the three groups in Table 2, and a rate is selected from the range of the uplink rate of the rate range pair as the uplink rate of the first service expected by the terminal device.

[0254] It should be noted that the carrying method of the response information is the same as the carrying method of the response information in implementation method 2-1. For details, please refer to the description in implementation method 2-1 and will not be repeated here.

[0255] In some implementations, if the first information sent by the network device to the first network element includes the first uplink rate range and / or the first downlink rate range, and the response information indicates the uplink rate of the first service, then after receiving the response information, if the uplink rate of the first service indicated by the response information is different from the current uplink rate of the first service, the network device sends the first information to the terminal device, and the first information includes the uplink rate of the first service. If the uplink rate of the first service indicated by the response information is the same as the current uplink rate of the first service, the first information is not sent to the terminal device. The network device first notifies the first network element of the first information, and the terminal device does not need to know the first associated information, which helps to reduce the information flow of air interface transmission.

[0256] In some implementations, if the first information sent by the network device to the first network element includes a first uplink rate range and / or a first downlink rate range, and the response information indicates the uplink rate of the first service expected by the first network element, then after receiving the response information, if the uplink rate of the first service expected by the first network element indicated by the response information is different from the uplink rate of the current first service, and the network device recognizes the uplink rate of the first service expected by the first network element, the network device sends the first information to the terminal device, the first information including the uplink rate of the first service, and the uplink rate of the first service is the uplink rate of the first service expected by the first network element; if the uplink rate of the first service expected by the first network element indicated by the response information is the same as the uplink rate of the current first service, the first information is not sent to the terminal device.

[0257] In some implementations, if the first information sent by the network device to the terminal device includes a first uplink rate range and / or a first downlink rate range, and the response information indicates the downlink rate of the first service, then after receiving the response information, if the downlink rate of the first service indicated by the response information is different from the current downlink rate of the first service, the network device sends the first information to the first network element, and the first information includes the downlink rate of the first service. If the downlink rate of the first service indicated by the response information is the same as the current downlink rate of the first service, the first information is not sent to the terminal device. The network device first notifies the terminal device of the first information. Due to the fast air interface information interaction, the uplink rate of the first service of the terminal device can be quickly adjusted, which helps to quickly relieve congestion when the network is congested.

[0258] In some implementations, if the first information sent by the network device to the terminal device includes a first uplink rate range and / or a first downlink rate range, and the response information indicates the downlink rate of the first service expected by the terminal device, then after receiving the response information, if the downlink rate of the first service expected by the terminal device indicated in the response information is different from the current downlink rate of the first service, and the network device recognizes the uplink rate of the first service expected by the terminal device, the network device sends the first information to the first network element, the first information including the downlink rate of the first service, and the downlink rate of the first service is the downlink rate of the first service expected by the terminal device; if the downlink rate of the first service indicated by the response information is the same as the current downlink rate of the first service, the first information is not sent to the terminal device.

[0259] In some implementations, if the response information instructs the network device to re-initiate rate adjustment of the first service, the network device may re-initiate a new round of rate adjustment of the first service after receiving the response information to determine a reasonable first uplink rate and / or first downlink rate.

[0260] For ease of understanding, the following takes the example of the network device knowing the first network element known first association information. Figure 6This section introduces the solution for implementing method 2-2. Figure 6 Includes steps S610 to S640.

[0261] Assume that the first service is an XR service, the network device is an access network device, the access network device sends the first information to the first network element through the core network network element, the first network element is an XR server, the access network device is a gNB, and the core network network elements include SMF and AMF.

[0262] In step S610, the gNB sends first information to the terminal device.

[0263] Based on the wireless condition information, the gNB determines the uplink rate and the first downlink rate range of the XR service, and sends the first information to the terminal device through the RRC message. The RRC layer of the terminal device receives the first information and notifies the application layer of the terminal device. The first information includes the uplink rate of the XR service.

[0264] In step S620, the gNB sends first information to the XR server.

[0265] The gNB notifies the AMF of the first information through the NG interface message, and then forwards it to the XR server through the SMF. The first information includes the uplink rate and the first downlink rate range of the XR service.

[0266] In step S630, the XR server selects a downlink rate of the XR service from the first downlink rate range.

[0267] The XR server selects a downlink rate of the XR service from a first downlink rate range based on the first association information.

[0268] In step S640, the XR server sends a response message to the gNB.

[0269] If the XR server selects the downlink rate of the XR service from the first downlink rate range, the response information sent by the XR server to the gNB indicates the downlink rate of the XR service; if the XR server does not select the downlink rate of the XR service from the first downlink rate range, the response information sent by the XR server to the gNB instructs the network device to re-initiate rate adjustment of the XR service.

[0270] Implementation method 2-3: The first information includes the uplink rate of the first service or the downlink rate of the first service.

[0271] In some implementations, the first information received by the terminal device includes the uplink rate of the first service, and the terminal device sends response information to the network device, where the response information is used to indicate the downlink rate of the first service or the range of the downlink rate.

[0272] In some implementations, the downlink rate or the range of downlink rates of the first service indicated by the response information is determined based on the association relationship.

[0273] In some implementations, the downlink rate or the range of the downlink rate is determined based on an association relationship, which can be understood as the terminal device receiving the first information determines the downlink rate or the range of the downlink rate of the first service that has an association relationship with the uplink rate of the first service based on the association relationship indicated by the first association information and the uplink rate of the first service included in the first information. For example, the first association information refers to Table 1, the terminal device receives the first information, and the uplink rate of the first service included in the first information is C in Table 1, then the terminal device can determine that the downlink rate of the first service is D based on Table 1. For another example, the first association information refers to Table 2, the terminal device receives the first information, and the uplink rate of the first service included in the first information is within the range [C, D], then the terminal device can determine that the range of the downlink rate of the first service is [C′, D′].

[0274] In some implementations, the first information received by the first network element includes a downlink rate of the first service, and the first network element sends response information to the network device, where the response information is used to indicate an uplink rate or a range of uplink rates of the first service.

[0275] In some implementations, the uplink rate or the range of uplink rates of the first service indicated by the response information is determined based on the association relationship.

[0276] In some implementations, the uplink rate or the range of the uplink rate is determined based on an association relationship, which can be understood as follows: the first network element receives the first information, and determines the uplink rate or the range of the uplink rate of the first service that has an association relationship with the downlink rate of the first service based on the association relationship indicated by the first association information and the downlink rate of the first service included in the first information. For example, the first association information refers to Table 1, the first network element receives the first information, and the downlink rate of the first service included in the first information is D in Table 1, then the first network element can determine that the uplink rate of the first service is C based on Table 1. For another example, the first association information refers to Table 2, the first network element receives the first information, and the downlink rate of the first service included in the first information is within the range [C′,D′], then the terminal device can determine that the range of the uplink rate of the first service is [C,D].

[0277] In some implementations, after receiving the response information sent by the first network element, the network device sends the first information to the terminal device, where the first information includes the uplink rate of the first service.

[0278] In some implementations, the network device receives the response information sent by the first network element. If the response information indicates a range of uplink rates, the network device selects an uplink rate of the first service from the range of uplink rates and sends first information to the terminal device, where the first information includes the uplink rate of the first service. For example, if the range of the uplink rate of the first service indicated by the response information is [C, D], the network device selects a value C from the range. 1 , as the uplink rate of the first service, and sends first information to the terminal device, the first information including that the uplink rate of the first service is C 1 .

[0279] It should be noted that the carrying method of the response information is the same as the carrying method of the response information in implementation method 2-1. For details, please refer to the description in implementation method 2-1 and will not be repeated here.

[0280] In some implementations, after receiving the response information sent by the terminal device, the network device sends first information to the first network element, where the first information includes a downlink rate of the first service.

[0281] In some implementations, the network device receives a response message sent by the terminal device. If the response message indicates a range of downlink rates, the network device selects a downlink rate of the first service from the range of downlink rates and sends first information to the first network element. The first information includes the downlink rate of the first service. For example, if the range of the downlink rate of the first service indicated by the response message is [C′, D′], the network device selects a value C′ from the range. 1 , as the downlink rate of the first service, and sends first information to the first network element, the first information including the downlink rate of the first service is C′ 1 .

[0282] For ease of understanding, the following takes the example of the network device knowing the first network element known first association information. Figure 7 This section introduces the solution for implementing method 2-3. Figure 7 Includes steps S710 to S740.

[0283] Assume that the first service is an XR service, the network device is an access network device, the access network device sends the first information to the first network element through the core network network element, the first network element is an XR server, the access network device is a gNB, and the core network network elements include SMF and AMF.

[0284] In step S710, the gNB sends first information to the XR server.

[0285] Based on the wireless conditions, the gNB determines the downlink rate of the XR service, and notifies the AMF of the first information through the NG interface message, which is then forwarded through the SMF to notify the XR server of the first information, where the first information includes the downlink rate of the XR service.

[0286] In step S720, the XR server determines the uplink rate of the XR service.

[0287] The XR server determines the uplink rate of the XR service based on the first association information.

[0288] In step S730, the XR server sends a response message to the gNB.

[0289] The response information sent by the XR server to the gNB indicates the uplink rate of the XR service.

[0290] In step S740, the gNB sends first information to the XR server.

[0291] When the gNB receives the response information, it sends the first information to the terminal device through the RRC message. The RRC layer of the terminal device receives the first information and notifies the application layer of the terminal device. The first information includes the uplink rate of the XR service.

[0292] The above three implementation methods respectively introduce a method in which a network device does not obtain the first associated information and sends the first information to the terminal device and / or the first network element to adjust the rate of the first service. In some scenarios, the above three implementation methods can be used alone. In other scenarios, the above three implementation methods can be used in combination with each other. The following describes a method for combining the three implementation methods.

[0293] In some implementations, implementation 2-1 is combined with implementation 2-2, and the network device sends first information to the terminal device or the first network element, where the first information includes a first uplink rate and a first downlink rate range. The terminal device or the first network element determines whether the first uplink rate is reasonable based on the first associated information. If the first uplink rate is reasonable, the downlink rate of the first service is selected from the first downlink rate range.

[0294] In some implementations, if the first associated information includes an uplink rate and / or a downlink rate, determining whether the first uplink rate is reasonable can be understood as determining whether the first uplink rate is the same as the uplink rate. If the first uplink rate is the same as the uplink rate, the first uplink rate is considered to be reasonable; if the first uplink rate is different from the uplink rate, the first uplink rate is considered to be unreasonable.

[0295] In some implementations, if the first associated information includes a range of uplink rate and / or a range of downlink rate, determining whether the first uplink rate is reasonable can be understood as determining whether the first uplink rate is within the range of the uplink rate. If the first uplink rate is within the range of the uplink rate, the first uplink rate is considered to be reasonable; if the first uplink rate is not within the range of the uplink rate, the first uplink rate is considered to be unreasonable.

[0296] In some implementations, if the first associated information includes an uplink rate and / or a downlink rate, and the first uplink rate is reasonable, selecting the downlink rate of the first service from the first downlink rate range can be understood as selecting a rate pair whose uplink rate is the same as the first uplink rate and whose downlink rate is within the first downlink rate range from the multiple groups of uplink rates and downlink rates indicated by the first associated information, wherein the uplink rate is used as the uplink rate of the first service, and the downlink rate is used as the downlink rate of the first service. For example, the first associated information includes an uplink rate and a first ratio, and the first associated information is shown in Table 3, which indicates three groups of uplink rates and downlink rates. From the three groups of uplink rates and downlink rates, a rate pair whose uplink rate is the same as the first uplink rate and whose downlink rate is within the first downlink rate range is selected, wherein the uplink rate is used as the uplink rate of the first service, and the downlink rate is used as the downlink rate of the first service.

[0297] In some implementations, if the first association information includes an uplink rate range and / or a downlink rate range, and the first uplink rate is reasonable, and the downlink rate of the first service is selected from the first downlink rate range, it can be understood that, from the multiple groups of uplink rate ranges and downlink rate ranges indicated by the first association information, a rate range pair in which the first uplink rate is within the uplink rate range and the downlink rate range has an intersection with the first downlink rate range is selected, and the downlink rate of the first service is selected from the intersection of the downlink rate range and the first downlink rate range, and the first uplink rate is used as the uplink rate of the first service. For example, the first association information refers to Table 2, which indicates three groups of uplink rate ranges and downlink rate ranges, and from the three groups of uplink rate ranges and downlink rate ranges, a rate range pair in which the first uplink rate is within the uplink rate range and the downlink rate range has an intersection with the first downlink rate range is selected, and the downlink rate of the first service is selected from the intersection of the downlink rate range in the rate range pair and the first downlink rate range, and the first uplink rate is used as the uplink rate of the first service.

[0298] In some implementations, if the first uplink rate is judged to be reasonable and the downlink rate of the first service is selected from the first downlink rate, the terminal device or the first network element sends a response message to the network device, and the response information indicates that the first uplink rate is the uplink rate of the first service and the downlink rate of the first service.

[0299] In some implementations, if it is determined that the first uplink rate is unreasonable, and / or the downlink rate of the first service is not selected from the first downlink rate range, the terminal device or the first network element sends a response message to the network device, and the response message indicates one or more of the following: the network device re-initiates rate adjustment of the first service; the uplink rate and / or downlink rate of the first service expected by the terminal device or the first network element.

[0300] In some implementations, implementation 2-1 is combined with implementation 2-2, and the network device sends first information to the terminal device or the first network element, where the first information includes a first downlink rate and a first uplink rate range. The terminal device or the first network element determines whether the first downlink rate is reasonable based on the first associated information. If the first downlink rate is reasonable, the uplink rate of the first service is selected from the first uplink rate range.

[0301] In some implementations, if the first associated information includes an uplink rate and / or a downlink rate, determining whether the first downlink rate is reasonable can be understood as determining whether the first downlink rate is the same as the downlink rate. If the first downlink rate is the same as the downlink rate, the first downlink rate is considered to be reasonable; if the first downlink rate is different from the downlink rate, the first downlink rate is considered to be unreasonable.

[0302] In some implementations, if the first associated information includes a range of uplink rate and / or a range of downlink rate, determining whether the first downlink rate is reasonable can be understood as determining whether the first downlink rate is within the range of downlink rate. If the first downlink rate is within the range of downlink rate, the first downlink rate is considered to be reasonable; if the first downlink rate is not within the range of downlink rate, the first downlink rate is considered to be unreasonable.

[0303] In some implementations, if the first association information includes an uplink rate and / or a downlink rate, and the first downlink rate is reasonable, selecting the uplink rate of the first service from the first uplink rate range can be understood as selecting a rate pair whose downlink rate is the same as the first downlink rate and whose uplink rate is within the first uplink rate range from the multiple groups of uplink rates and downlink rates indicated by the first association information, wherein the uplink rate is used as the uplink rate of the first service, and the downlink rate is used as the downlink rate of the first service. For example, the first association information includes an uplink rate and a first ratio, and the first association information is shown in Table 3, which indicates three groups of uplink rates and downlink rates. From the three groups of uplink rates and downlink rates, a rate pair whose downlink rate is the same as the first downlink rate and whose uplink rate is within the first uplink rate range is selected, wherein the uplink rate is used as the uplink rate of the first service, and the downlink rate is used as the downlink rate of the first service.

[0304] In some implementations, if the first association information includes an uplink rate range and / or a downlink rate range, and the first downlink rate is reasonable, and the uplink rate of the first service is selected from the first uplink rate range, it can be understood that, from the multiple groups of uplink rate ranges and downlink rate ranges indicated by the first association information, a rate range pair in which the first downlink rate is within the downlink rate range and the uplink rate range and the first uplink rate range have an intersection is selected, and the uplink rate of the first service is selected from the intersection of the uplink rate range and the first uplink rate range, and the first downlink rate is used as the downlink rate of the first service. For example, the first association information refers to Table 2, which indicates three groups of uplink rate ranges and downlink rate ranges, and from the three groups of uplink rate ranges and downlink rate ranges, a rate range pair in which the first downlink rate is within the downlink rate range and the uplink rate range and the first uplink rate range have an intersection is selected, and the uplink rate of the first service is selected from the intersection of the uplink rate range in the rate range pair and the first uplink rate range, and the first downlink rate is used as the downlink rate of the first service.

[0305] In some implementations, if the first downlink rate is judged to be reasonable and the uplink rate of the first service is selected from the first uplink rate, the terminal device or the first network element sends a response message to the network device, and the response information indicates that the first downlink rate is the downlink rate of the first service and the uplink rate of the first service.

[0306] In some implementations, if it is determined that the first downlink rate is unreasonable, and / or the uplink rate of the first service is not selected from the first uplink rate range, the terminal device or the first network element sends a response message to the network device, and the response message indicates one or more of the following: the network device re-initiates rate adjustment of the first service; the uplink rate and / or downlink rate of the first service expected by the terminal device or the first network element.
